But on closer inspection, the math doesn’t quite work.
Yes, it is good that a random armed man was able to take out a would-be mass shooter in Indiana, and yes it could have been much worse there: The shooter used an AR-15-style rifle, had other weapons at the ready and had more than 100 rounds of ammunition — and as is so often the case in mass shootings, he had purchased his fatal weapon legally.
Three people dead is not a win just because it could have been much worse. Three people joining the tens of thousands already killed this year by guns should be a mark of shame, not a rallying cry for more guns. The fact that this is the best story gun proponents have — “three people were killed but it would have been an even more horrific bloodbath if not for another armed citizen” — should demonstrate how wholly bankrupt their position truly is.
The problem isn’t a lack of good guys. The problem is all the guns.
